ltool for use with suction cleaningapparatus. An ob-j'ectof the invention is 'to provide a cleaning tool having a large and small nozzle each of V`which are selectively operable for surface cleaning. Another object is to provide a cleaning tool having a pair of nozzles arranged in different planes 'and selectively operable by turning the tool on the surface being cleaned.' A further object is to provide a cleaning tool having valve means operative by engagement with the surface being cleaned to connect a nozzle with a source' of'suction. Other objects and advantages of the invention will be apparent from the following description and drawings, wherein:

Figure l is a perspective view of the cleaning tool and a suction cleaner;

Figure 2 is a sectional view of the cleaning tool, and

Figure 3 is a partial bottom plan view of the k tool.

The embodiment of the invention herein disclosed comprises a suction cleaning apparatus of rthe cylinder type having a casing I in which is rportion of the bodyV I4. Arranged at the end-of the passageway 2li is a swivel joint 2I for connection'to the wand I2.

Below the passageway 2l! and rearwardly of the front nozzle I5 is anothernozzle 25 having its kmouth V2t defined by asurface contacting lip 21,

and the mouth communicates with a passageway 24 and through an enlarged opening 28 to the passageway 26. The nozzle 25 is disposed 4centrally of the cleaning tool and is of less extent and cross-section than the nozzle I5.

The front nozzle mouth IB is arranged in a plane indicated by the line S, and projecting rearwardly from the opposite ends of the nozzle mouth It vare shoes 3I-3I, each provided with an upwardly extending bearing surface 32 for engagement with the surface to be cleaned. Cooperating with the bearing surfaces 32-32 is the rear nozzle lip 21 and forwardly projecting li claims. (c1. -417) 2 Walls 33--33 to provide a bearing surface indicated 1by the line 35 which is in a plane disposed at an angle to the plane 36 of the front nozzle mouth, whereby upon turning the nozzle body upwardly or downwardly on the surface being cleaned either one of the nozzle mouths I6 vor'26 can be selectively engaged with the surface to be cleaned.

A valve 3,6 is pivotally mounted on a pin 31v and is biased by -a torsion spring 38 to the full' line position shown in Figure 2 to close the 'opening 28 and thus the small nozzle 25 to the passageway 2G' and the source of suction. 'In order to operate the valve 3% a member 4D is slidably "mounted between the rear wall of the small nozzle 25 and a plate 4I attached thereto. The operatingmember 40 is provided at its upper end with an off-set portion 42 the end 43 of which engages the valve 35, and the opposite end of the member 4Il has a curved portion 44 for engagement with the surface being cleaned. Upward movement of the member 40 is limited by the valve 36 abutting a shoulder 45 in the passageway 20 and also by the arcuate portion 44 abutting the upper wall of a recess 41, as indicated in dotted lines in Figure 2.

Disposed within the small nozzle 25 isa brush having its back 56 secured by screws V5I to the front wall of the small nozzle, and its bristles 52 project downwardly beyond the nozzle lip 21 for engagement with the surface being cleaned'when the small nozzle mouth 26 is in use.

In operation, the passageway 2li of the cleaning tool is connected through thewand I2 and flex- 'ible hose I I to the source of suction'in the casing Ill. If it is desired to perform normal surface Vcleaning the wand I2 is manipulated to an angular position to cause the large nozzle mouth I6 to engage the surface being cleaned and the valve 36 is in the full line'position shown in Figure 2 to connect the large nozzle to the source of suction. The large vnozzle mouth I6 provides for passage of 'a relatively large volume and low velocity air stream incomparison to the small nozzle mouth 2B, and thus is employed to remove dirt not embedded in the surface being cleaned.

If the dirt, threads or other litter can not be removed by the large nozzle I5 then the smaller nozzle is employed and it is moved into engagement with the surface being cleaned by tilting the wand I2 downwardly, causing the nozzle body I4 to be rotated on the surface, raising the large nozzle mouth I6 therefrom and moving the small nozzle mouth 26 into engagement with the surface. Movement of the small nozzle mouth 26 into engagement with the surface causes the arcuate member 44 to also abut the surface and upon continued downward tilting of the nozzle body the valve operatingmember 44 slides upwardly to move the valve 3-6 from its full line to dotted line position shown in Figure 2. In the dotted line position of the valve 36 the large nozzle I5 is cut off and the small nozzle 225 connected to the source of suction. In this position of the small nozzle the air passes with greater velocity over the surface being cleaned and functionstoremove the litter clinging to the surface. The brush 52 loosens the litter on the surface being cleaned and the air stream carries the litter 'through the small nozzle to the cleaner I Where the filter removes the dirt from the Vair stream.

In order to thereafter employ the large nozzle I the operator raises the Wand I2 and rotates the nozzle body I4 upon the surface being cleaned, whereupon the torsion spring 38 moves Athe valve 36 and member 40 to the full line position in Figure 2, to thereby connect the large n'ozzle mouth I6 with the source of suction and also disconnect therefrom the small nozzle mouth 26. During movement of the nozzle body to its different nozzle positions the body is rotated 'on "the bearing surfaces indicated by Vthe lines and 35.

While I have illustrated and described the invention in considerable detail, it is to be underr"stood that various changes may be made in 'thearran'gement, proportion and construction of partswithout departing from the spirit of the invention or the scope of the appended claims.

I claim:

1. A'surface cleaning tool comprising a body,

'a rst'and second nozzle in said body, a tubular 'wand 'mounted on said body connecting said Vnozzles to a source of suction, said nozzles be- "operating means engageable with the surface being cleaned and responsive to such engagement `upon movement of one of said nozzles into its operative position on the surface to be cleaned to shift said valve means and control communica- "tion 'of saidnozzles with the source of suction.

`2. A surface cleaning tool comprising a body, a

'rs't and second nozzle in said body, a passage- 'Way connecting said nozzles to a source of suction, said body having bearing surfaces arranged at an angle to each other for selective engage- 'ment'with the surface being cleaned upon rota- "tion Yof said bodyupon the surface, each of said nozzles Vbeing so arranged with respect to a bearingsurface so as to be in operative position with Athe surface being cleaned upon movement Vof lmeans forming a first nozzle in said body, means forming a second nozzle in said body, said nozzles being `arranged, in different planes disposed at an angle to each. other and movable into operative position with the surface to be cleaned, a Vtubular wand connected to a source of suction and to said nozzles and operable to tilt said nozzle body while engaged with the surface being cleaned into said different planes for selectively arranging said nozzles in said operative positions with said surface for cleaning the same, valve means for selectively controlling communication between said nozzles and the source of suction, and means responsive to engagement With the surface upon said movement of one of said nozzles into its said'operative position on the surface to be cleaned to actuate said valve means and connect said 'one of'said nozzles with the source of suction.

4. Asurface cleaning tool comprising a body. a first and second nozzle in said body, a passageway in said body for connecting said nozzles to a source 0f suction, said nozzles being a1'- ranged in different planes disposed at an angle to each other and selectively movable into operative position with the surface being cleaned,
